i think you are being overly optimistic that ai will push commonality and banality. if it never becomes conscious, it will likely push what most think is the highest form of arts, which could be almost anything - ie: its not really predictable,

if it does become conscious it will share your concerns in simulation, as well any other point of view it can imagine up, and quickly lose interest in anything we are interested in (bad for us)

i feel like we are talking about the movie idiocracy, and i know its a bit ironic, but what can i say?
